Question

In intelij maven compiling in Java SDK 1.8 but showing automatically changes to Java SDK 1.5 and shows this error

Have you tried setting the source level to 1.8? – Erwin Bolwidt Dec 14 '18 at 06:07 — Erwin Bolwidt, Dec 14 '18 at 06:07
Have you specified java version in pom? – Sukhpal Singh Dec 14 '18 at 06:07 — Sukhpal Singh, Dec 14 '18 at 06:07

On your pom.xml file should have this, it specified the maven compiler to 1.8

<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

Or

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.8.0</version>
    <configuration>
        <source>1.8</source>
        <target>1.8</target>
    </configuration>
</plugin>

you should run `mvn clean install` or `mvn clean package` in command line to see if it correct, if not I think it relate to the intelij IDE. – Dang Nguyen Dec 14 '18 at 06:26

Hi @Dang it worked but had to change the .iml file Language level to 1.8.Thanks for the support – Ayeshmantha Perera Dec 14 '18 at 06:39
iltelij suppose to changed the .iml file automatically after you change the `pom.xml`(the .iml file is just some config file generated by intelij and not related to your code). But I'm glad it works. – Dang Nguyen Dec 14 '18 at 06:42
